Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.
It is reported that in the phase-out of coal-fired boiler reconstruction project, Jinan City, Shandong Province Finance Bureau has appropriated out of the transformation of coal-fired boilers municipal county area of awards and subsidies 310 million yuan for the enterprises, units out of coal-fired boilers and special awards subsidy.
The allocation of financial awards complement funds, aims to accelerate the transformation of the city's coal-fired boilers out of work, to further improve air quality, according to the municipal government office "on accelerating the transformation of the city's coal-fired boilers out of work notice" (Ji Zheng Ban word  4) the requirements of the embodiment.
According to the municipal environmental protection department statistics, in 2017 the transformation range Jinan included in the elimination of 35 tons of steam and the following business units of coal-fired boilers 323 units, 1605 tons of steam coal-fired boiler units of 69, 189 tons of steam; the need for ultra-low emissions the transformation of more than 35 tons of steam coal-fired boilers of 94, 14 960 tons of steam. The issued rewards and subsidies, the Municipal Finance Bureau to take "the first disbursement, after the liquidation," the way out of the transformation of the inclusion of ultra-low emissions and transform the scope of coal-fired boilers in 2017 the implementation of full coverage, in accordance with the award criteria make a one-time pre dial counties and districts, counties and districts in the implementation of rehabilitation programs out of the boiler can award up early disbursement of funds of enterprises and units, to be enterprise, unit after the completion of the transformation carried out of funds liquidation.
Meanwhile, the Municipal Finance Bureau called on counties and district financial departments should closely cooperate with the environmental protection department, the main responsibility for the effective implementation of good out of the transformation of coal-fired boilers, will award up funds earmarked for municipal 35 tons of steam coal-fired boilers and substitution and elimination more than 35 tons of steam coal-fired boiler reconstruction project of ultra-low emissions (including troops out of coal-fired boiler replacement) cash incentives and subsidies, strengthen capital management, give full play to the financial capital efficiency.
Select the first vertical fuel steam boiler to know what parameters? Steam boilers have the following main parameters: 1, Rated evaporation Rated evaporation is power steam boiler, steam boiler is the most important parameter, usually expressed in tons evaporation, that is, we usually say how many tons of boiler. 2, rated steam pressure rated steam pressure means that the steam pressure generated in the steam boiler, generally expressed in MPa or kg. 1MPa is 10 kg, like laundry, all hospitals, factories and the like conventional steam occasions the general use of low-pressure steam 1.0MPa or less. Only when using steam as a power to require the use of high-pressure steam. 3, where the steam temperature of said steam temperature, refers to the temperature of saturated steam. Saturated steam pressure and steam temperature are corresponding. Temperature of saturated steam at a pressure of 1MPa 184 ℃. 4, gas / oil / gas consumption fuel consumption is an important indicator of concern when choosing a steam boiler, which is directly related to the use of the running cost of the boiler. In the operation of the boiler, the fuel cost is very impressive, if just considering the purchase cost of buying a cheap but high energy boiler, which led to the late high operating costs, certain that it will be wasted. 5, the thermal efficiency of fuel consumption with the boiler thermal efficiency of boilers is inversely proportional. The higher thermal efficiency, lower fuel consumption of the boiler. Boiler thermal efficiency expressed as a percentage, the value is a more intuitive. 6, the boiler operating weight, size or location in the election of the steam boiler, it should find the place whether the load per unit area can withstand the weight of the steam boiler, and if there is enough space to place the steam boiler maintenance and reserve space.
Natural gas boiler once a day to check how long it takes much time to check the gas boiler natural gas boiler includes a gas water boiler, gas hot water boiler, gas vertical fuel steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath , gas boilers name suggests refers to the fuel gas boilers, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. According to market surveys, gas boilers and coal-fired boilers scheduled inspection time, like once a year, April 19, 2018, the special prosecutor in Daxing District in Beijing Yizhuang three sheep, six 68MW heating Limited (approximately equal to 40T) of gas heating boiler regular inspections. On-site inspectors checked the calendar year of inspection reports, operating records, factory data boiler, the operator asked in detail about the boiler operating conditions during the winter heating, internal inspection carried out in accordance with these four boiler inspection program. Focus on examination of water tube boilers, membrane wall inside the furnace tubes, burners, fire insulation materials, while making inspection records.
